中文摘要 | 本研究設計的機械式遮光設施是以馬達為動力源,蝸輪減速機、傳動軸、皮帶輪、惰輪、尼龍索等為傳動機構,控制箱、極限開關等控制開閉遮光網。 經實驗獲得如下之結論: 一、遮光網可以降低進入溫室的太陽輻射量及照度,其遮光效果主要由遮光率來決定。 二、遮光網裝在溫室屋頂上,可以降低溫室溫度,以50%遮光率之遮光網為例,約可降溫0.5°C至1.5°C之間。 三、間隔式遮光板之遮光效果成週期性變化。 四、臺灣天氣變化量大,即使同一日的天氣,陰晴下雨變化亦大,所以溫室遮光設施機械化後,才能適時的機動性開閉遮光網,以獲得植物適宜生長的照度環境。 |
英文摘要 | The motor is adopted as the actuating element in this study. The power is transmitted through wormgear reducer, shaft, pulleys, idlers and nylon ropes. A control panel and the related electronic circuit are used to facilitate the opening or closing action of the shading net. The results obtained from experiments are as follows: 1. The shading net can reduced the solar radiant flux density and the light intensity entering into the greenhouse. The shading effect is mainly effected by the shading rate. 2. The shading ne mounted above the roof of the greenhouse will reduce its inside temperature. In the case that the shading rate is fifty percent, the temperature reduced will be between 0.5°C to 1.5°C. 3. The shading effect changed periodically as the sun light was blocked by the evenly spaced laths under the shading net. 4. The local weather alters rapidly in the daytime, therefore it is necessary to mechanized the opening or closing of the shading net according to the varying conditions of weather to ensure the suitable environment for the plant growth. |
